1. The teleprompters are there, but it sounds like he's riffing.

[FLyellowdog]

3. Journalist Tweeters are saying this is what he's doing. Awesome.nt

[valerief]

2. He's definitely riffing. They'll be hard-pressed to get him off the stage! nt

[unblock]

4. maybe the teleprompter just says "vamp"?

[CherokeeDem]

5. He has a teleprompter...

but someone posted that for every one line of his prepared speech, he's ad-libbing two or three...

Big Dawg Rocks!!!!

[Avalux]

6. Twitter says he's gone off script. There are lines there, but he's adding and changing.

7. Yes, is fab

[Stinky The Clown]

8. Both

He lost his way a few minutes ago and you could see him go to the teleprompter . . . . . but he's not reading a speech. He's working from notes.

He's the best you'll ever see.

9. He is going way off the riff...I'm reading his speech..

marvelously,

10. I love our country...

and I know we're coming back. For more than 200 years, through every crisis, we've always come out stronger than we went in. And we will again as long as we do it together. We champion the cause for which our founders pledged their lives, their fortunes, their sacred honor – to form a more perfect union.

If that's what you believe, if that's what you want, we have to re-elect President Barack Obama.

11. He's the master of Improv.

[Chiyo-chichi]

12. But how did he e-mail me while he was still speaking? That's a feat!

Nevermind... two-term President Clinton is onstage with two-term President Obama! WOOT!

13. Impressive just impressive

Best Nomination Speech I've ever heard.

14. That was an amazing bit of work..wow

[Jennicut]

15. How does he keep all that info in his head?

He really is an amazing speaker. Thank you, President Clinton, for addressing all the Repub lies.

[justabob]

18. accessing it is the feat

Lots of people have the info, but they aren't so fluent with it or articulate it so well. He did an amazing job.

[undeterred]

16. That's typical for Clinton

I got to be onstage behind him while he was campaigning for our Democratic Governor in WI a few years ago. When he arrived he asked one of the congresspeople for a little information and wrote it down-local names got plugged into the speech. He went on for almost an hour and a half talking - off the cuff the whole time. It just pours out of him.

17. He's TERRIFIC, a real natural, none can ever compare to Big Dog! nt!
